Y The members 44 and 51. are pivoted to each other and likewise to alink member52 at the point 53 for the purpose of actuatin a fresh airdamper 54 connected to said and which will thereby open the fresh airtube 55 upon a rise of .the temperature within the tray and will alsoautomatically close the saine upon the lowering ofthe temperaturethereof, all of the same be' accomplished through the said thermostautlimember and its connect-ing means. The said fresh air tube 55 alines witha passage or stub pipe 56 in the rear wall of the casing 25 5and feedsfresh air to a' point slightly removed from the center of the tray andbeneath thewire bottom .37 thereof, it bein "noted that all of the-levermembers as we `as the fresh air flue are positioned between thiswirebottom and the main bottom 36 A thereof.

The partial operation of the device having alread been described, the'complete workings ereof are believed to be now ap arent.

ith the superposed trays in any desired l 100 ition as shown in Fig. 4,an excessive rise in temperature within an intermediate tray will openthe fresh-air inlet beneath the same and simultaneously -will also openboth of the side hot air dampers forallowing the hot air within the trayto pass outwardly and upwardly to enter anyother tnry in whichadditional heat is nired a for which reason its respective side damper-sas well as its fresh air damper arel closed as shown in the upper trayin 4.

`While an outer 'cas' 25 or containing thetrays is desirable, it will beevident that any number f superposed trays mais; be-employed withoutsuch a casing but wit Amerely a top member positioned. upon theuppermost tray, a self-re lating separate tra system being contemp ated.f
